First ground-based remote sensing dataset for atmospheric Ethane (C2H6) over eastern China Y. W. Sun and Y. Hao https://doi.org/10.6084/m9.figshare.13020545
Short summary
The variability, sources, and transport of ethane (C2H6) over eastern China from 2015 to 2020 were studied using ground-based Fourier transform infrared (FTIR) spectroscopy and GEOS-Chem simulations. C2H6 variability is driven by both meteorological and emission factors. The reduction in C2H6 in recent years over eastern China points to air quality improvement in China.
